What is Canon C-Log and Why You Should Use It


With the addition of Canon Log (C-Log), Canon has brought the Cinematic video production look to the DSLR body. As you can see from the test shots the look of Canon Log is very different from the original video output. The final image is also much more flexible when editing in post. The Canon EOS Cinema Log’s color will be a great addition to many videographers arsenal.

Canon’s C-Log maximizes the image sensor to obtain a greater dynamic range, making footage captured by the EOS 5D Mark IV’s footage more flexible in post. Using C-Log will reduce loss in detail within the highlights and shadows.

Using C-LOG

To use the Canon Log, the camera must be set to Manual Mode (M), and Camera needs to be set to Live View.

Once you activate Canon Log, you will be given options to customize the image that you wish to capture. In Log you can adjust the Sharpness, Saturation, and Hue.

There is also an option to turn on View Assist, when this is activated you can set a picture style and it will be displayed on the back LCD. (It is important to note that View Assist is not the final look of you captured video it is just at preview of a certain picture style, much like shooting RAW stills with a picture mode set).  (View Assist Settings will not be visible during in camera video playback)

This update to the Canon EOS 5D Mark IV will in no way affect any of the older features in the camera unless C-Log is set to ON. When it is set to OFF the camera functions as normal.

General Information For Shooting with LOG set to ON:

  • When Log is set the following features will not be available: Auto Lighting Optimizer, Highlight Tone Priority, Time-Lapse Movie, and HDR Movie.
  • You will not be able to use auto ISO. (ISO will need to be set manually)
